Material code recording and reading method and devices designed for protection of products and control of their authenticity

ABSTRACT

Material code recording and reading method and devices designed for protection of products and control of their authenticity. The marking device  1  embeds a sign upon the product  4,  the marked product  5  is passed to camera  2  which films the product material structure around the sign and transfers the image to the recording device  3,  the latter records the database. The comparing alarm device  8  compares the icon from camera  7  with the icon from database  6  and alarms whether they are identical or not.

TECHNICAL SPHERE

The invention concerns a material code recording and reading method anddevices designed for protection of products and control of theirauthenticity applicable in the production process and control of money,documents, securities and articles if there is any suspicion about theirauthenticity.

FORMER AND PRESENT STATUS OF THE TECHNICAL MEANS AND APPROACHES

Recording and control methods and devices intended for markingprotection of securities and products against counterfeit by means ofwatermark, inks visible in ultraviolet or other light source; microbarcodes, metal thread with one-grade cipher, micro kinegrams,banderols, laser markings etc. are known. The control is made throughcomparison with naked or equipped eye.

The common disadvantage of the known methods and devices is that they donot suggest method to distinguish the original from its exact copy.

TECHNICAL NATURE OF THE INVENTION

The goal of the invention is to create material code recording andreading method and devices for protection of products and control oftheir authenticity. This invention is intended to achieve uniqueprotection aiming at differentiation of the original from its exactcopy. In fact the material code recording and reading method and thedevices designed for protection of products and control of theirauthenticity are the solution of the problem. The marking device embedsa sign upon the product, afterwards the marked product is passed to acamera to film the product structure around the sign and the image istransferred to the recording device. The latter records the database.The comparing alarm device reads the marking whereupon compares thepicture from the camera with the icon from the database and alarmswhether they coincide or not.

INVENTION PERFORMANCE EXAMPLES

With the marking device (Printer, Laser, Punching Machine etc.) a signis embedded on the product whereupon the marked product is transferredto the camera which films a part or the whole structure of the productmaterial around the sign. Next the image of the structure is moved to arecording device in order to record the database of the structure image,number and name of the product. The comparing alarm device and thecamera allow the reading of the marking from each point of the world.Both images from the camera and the database are compared by thecomparing alarm device. which alarms whether the icons are identical ornot.

1. Material code recording and reading method designed for protection of products and control of their authenticity which includes embedding of a sign upon product, filming of the material sturcture around the sign and entry of product and material structure icon database used for inspection by comparison of both database image and image from the camera.
 2. Material code recording and reading devices designed for protection of products and control of their authenticity which consists from marking device 1 to embed a sign upon the product 4; marked product 5 which is passed to camera 2 in order to film the product material structure around the sign and to transfer the image to the recording device 3 which, records the database whereupon the comparing alarm device 8 compares the icon from camera 7 with the icon from database 6 and alarms whether they are identical or not.
